Improvements
Minor documentation clean up regarding Superset compatibility

Bug Fixes
- Use uuid4 instead of uuid1 for generating client level session_ids, as well as use a new urllib3 PoolManager
when multiprocessing mode is detected. This should fix https://github.com/ClickHouse/clickhouse-connect/issues/194.
Thanks to [Guillaume Matheron](https://github.com/guillaumematheron) for filing the issue and digging into details.
The underlying problem is that the Python uuid1() is not guaranteed to be unique in a `forked` multiprocessing environment.
- Change log warning to debug message if numpy is not available for C bindings. This check is harmless if numpy
is not installed and should not have produced a warning. Fixes https://github.com/ClickHouse/clickhouse-connect/issues/195

Improvements
- Cython version upgraded to 3.0.0b2
- The block size (number of rows) for chunked/streaming inserts is now dynamically determined based on sample of
the insert data. This allows more efficient streaming of large inserts and significantly improves insert performance
in some circumstances.
- Pivoting row based data to native columns for inserts has been optimized in C. This improves insert performance
for large inserts of row oriented data.

Bug Fix
- The client will now validate that the `client_protocol_version` query parameter is actually received and used by the ClickHouse
server before assuming that data returned confirms to the expected protocol version. This fixes an incompatibility with the
current versions of CHProxy (and possibly other proxies that restrict the query parameters passed to the ClickHouse Server).
Note that other features that require the use of query parameters (such as server side bound query parameters) may also fail
because of this behavior in CHProxy. Fixes https://github.com/ClickHouse/clickhouse-connect/issues/191

Bug Fixes
- The client `command` method now accepts ClickHouse "external data." Closes https://github.com/ClickHouse/clickhouse-connect/issues/186
- Arrays of Python date and datetime objects are now correctly formatted when use as server side parameters. Fixes https://github.com/ClickHouse/clickhouse-connect/issues/188
- Fixed inserts of SimpleAggregateFunction columns with a LowCardinality type parameter. https://github.com/ClickHouse/clickhouse-connect/issues/187

Bug Fixes
- SQLAlchemy table reflection threw an exception for `SimpleAggregateFunction` columns. This has been fixed.
https://github.com/ClickHouse/clickhouse-connect/issues/180
- The client no longer logs an invalid warning for query types that did not return a timezone header.
https://github.com/ClickHouse/clickhouse-connect/issues/181
- Querying `SimpleAggregateFunction` columns with a LowCardinality type parameter was broken. This has been fixed.
https://github.com/ClickHouse/clickhouse-connect/issues/182
- The `query_arrow` method now correctly accepts the external_data parameter. https://github.com/ClickHouse/clickhouse-connect/issues/183
- The `query_arrow` method has been fixed for read only queries/settings. https://github.com/ClickHouse/clickhouse-connect/issues/184

New Feature
- A common setting `max_connection_age` has been added, which will ensure that HTTP connections are not reused forever (this
can help with certain load balancing issues. It defaults to 10 minutes

Bug Fix
- There was a critical issue when using zstd compression (the default) with urllib3 version 2.0+. This has been fixed.
